Re: Coleman Generator powerbase 4000 model #PM0543800
I have to leave a comment for cfa6094. Your pretty good at flexing your cyber muscles. I am a service tech in the repair field and deal with people like you all the time. If you are the owner of the equipment you should properly maintain your equipment. Sounds like you are not very organized. Sound more like crises management to me. Is mrfixit the only person you asked about this problem? One more thing, sound like you are a bit of a procrastinator to me. LOOK AT ME NO SPELL CHECK!

I assume that the spark plug are good and the gas line is clear. Try to adjust the gas line supply and default engine startup revolution settings try it full half and minimum back and forth it works. Other gen sets requires a mix of oil with its gas, please do it when it is required with exact proportion. Hope this helps. Goodluck.
Hi Joe, I had asked for a little clarification and have not received any information. I will answer this question based on the generator is in good working order and it is a recoil start. Open the petcock, (this is the fuel valve) and give it about a minute to fill the fuel bowl on the carburetor. If your generator has an engine an on/off kill switch, set to on. If the generator has an auto idle switch set it to off. If the engine has a throttle lever located under the carburetor, push it all the way down (full throttle). Pull the choke knob out completely, there is a detent on the choke for half choke, pull it past this for full choke. pull the recoil starter rapidly. As soon as the engine starts running push the choke knob to half choke, this will allow the engine to run smooth while it's warming up. Depending on the climate that you are in, warm up time will vary. After a minute or two in cold climates start pushing the choke knob in, if it starts to run poorly pull it back out too the half position and let it warm up some more. When you can posh the choke in without the engine faltering it is ready to go. In warmer climates you might be able to start the engine without the choke or in the halfway position. Robin Subaru makes some of the finest small engines available. I would choose a Robin over a Honda every time. I hope this gets your generator going, and once again this is based on the generator being in good working order. Good luck, Michael Burke.
It is possible that it may be having trouble if you have some bad gas but I would be more inclined to check the float to make sure it is not hanging up and allowing to much gas to get to engine. I would adjust idle and fuel mix screw all the way shut and then start opening them up about 1/4 turn at a time and try to start and run between adjustments.Only try to start it once or twice in between adjustments to avoid flooding. If you can get it to run good then turn screws one more time or until engine starts missing a little then slowly close until it runs smoothly.Hope this helps you. Thank you.
OK, you have a hard to find info on model. My first thought is that your choke is still on.
Does it have a manually activated choke? If so you know what to do, after she kicks, turn it off.
If it is one of the new Auto-choke units you may need to find the choke linkage and disengage
it that way. I have asked for a manual for your from UTS. We will see what they send, or dont!
As with all engines, if left in storage for long periods of time, use fuel stabilizer and try and start
the engine every 30 days and let it run for 10-15 minutes just to warm up and keep everything moving.
Most Generac generators have a lever for the choke that pulls out. So if the generator is being started for the first use or cold you should choke when starting . Let it run for 30-45 sec. then push it in . Once the engine has been run or warm you dont need to choke every time when starting .
Check the voltage sent to the field when running. It will probably be around 12 volts. You can try connecting a lantern battery BRIEFLY to the field to re-magnetize the field. Try bothe polarites.
Some have had a bad rectifier and one had a bad transformer that generaates the low voltage from the generated output. He had a broken wire from the winding to the wire from the transformer. He was able to reconnect the failed solder joint.
